A telephone numbering plan is a type of scheme used in telecommunication to assign telephone numbers to subscriber telephones or other telephony endpoints. Telephone numbers are the addresses of participants in a telephone network, reachable by a system of destination code routing.

The Numbering Plan is an addressing mechanism for communication networks, which enables routing of traffic to designated networks. NNP is sometimes used to identify different types of services.
